2. Mechanical Properties (Different Tempers)

The mechanical properties of 1050 aluminum vary significantly with processing conditions. Common tempers include annealed (O) and cold-worked (H):

Temper Tensile Strength (MPa) Yield Strength (MPa) Elongation (% in 50mm)

O (Annealed) 60 - 95 15 - 35 35 - 45

H14 125 - 145 110 - 130 6 - 12

H18 140 - 160 130 - 150 3 - 5

Note: Specific values may vary slightly due to production processes and testing standards.
